21. SUPERCHIPS NOTICE (APPLIES TO KITS SUPPLIED WITH SUPERCHIPS TUNER)
Regarding all GM vehicles with “ON-STAR” and Microtuner 2001. It has come to our
attention that GM vehicles equipped with “ON-STAR” communications may have trouble
being programmed with a Superchips Microtuner 2001. It appears the “ON-STAR” system
interrupts communications between the MT2001 unit and the vehicle’s PCM...” and after
cycling the ignition the vehicle can be started right back up.
Superchips is reviewing this and to temporarily correct for this situation, it is recommend-
ed that any vehicle to be programmed that has “ON-STAR” should follow these additional
steps FIRST.
1. Ensure the vehicle is off and keys are out of the ignition.
All model years up to 2002:
Locate “interior” fuse panel and remove QTY 2 SEO labeled fuses.
Locate “exterior” fuse panel and remove QTY 1 SEO labeled fuse.
2003-2004 models years: Remove the “INFO, RADIO, RADIO AMP” fuse locat-
ed on the exterior fuse panel.
2. Follow the instructions that came with the Microtuner.
Once programming is completed, ensure the vehicle is off and the keys are out of the
ignition and install the fuses in the correct locations.
On GMC trucks, the interior fuse panel should be located to the left of the instrument
panel/dash board. If the panel faces the door, open the door to gain full access.
On GMC trucks, the exterior fuse panel should be located under the hood on the right
hand side of the vehicle. It will be labeled Fuse Panel or similar.
NOTE: 2004 vehicles equipped with On-star that have aftermarket stereos will
experience problems withe the ability to re-program the vehicle’s ECM.
It is necessary to disconnect the aftermarket stereo from the factory
wiring harness before continuing with the programming procedure.
